Change Power Levels Anytime Without Plugging In

If you are tired of being locked into one tune for your 2011 Silverado or Sierra 2500HD or 3500HD, this Switch On The Fly package completely changes the game. With all five custom tunes loaded and ready, you can move from Optimized Stock to Sport, Street, Light Tow, or Heavy Tow while driving. There is no need to pull over and reflash the truck with a handheld every time your plans change. Heading to work empty in the morning and towing in the afternoon becomes simple and seamless. The Sport file delivers up to 135 rear wheel horsepower and 243 lb-ft of torque when you want maximum performance. When it is time to hook up a trailer, the dedicated tow tunes manage power and temperatures so you can stay in control. Best of all, your emissions equipment remains fully intact, so you gain serious flexibility without sacrificing compliance.

Advanced Custom Calibration With Integrated Tow And Performance Control

Behind the convenience is a fully custom calibration strategy developed from more than 100 changes to the factory programming. Each file is designed with a specific purpose, from aggressive acceleration in Sport mode to SMART EGT control in the Light Tow and Heavy Tow files. Air fuel ratio limits are built in to help control soot output, and the factory turbo brake remains functional across the calibrations. The included EFI Live AutoCal V3, also known as the SPADE device, provides professional level flashing and data logging capabilities. This system eliminates the need for wire splicing or sensor tampering, keeping the truck’s factory systems protected. When paired with recommended TCM tuning, torque converter lockup and shift strategy are optimized to better use the wider torque curve. The result is a 6.6L LML that feels refined, powerful, and adaptable to whatever the day demands.
